Observation of non-gaussian conductance fluctuations at low temperatures in Si:P(B) at the metal-insulator transition
Swastik Kar, A. K. Raychaudhuri, Arindam Ghosh
We report investigations of conductance fluctuations (noise) in doped silicon at low temperatures (TK) as it is tuned through the metal-insulator transition (MIT). The scaled…
Universal conductance fluctuations in three dimensional metallic single crystals of Si
Arindam Ghosh, A. K. Raychaudhuri
In this paper we report the measurement of conductance fluctuations in single crystals of Si made metallic by heavy doping (n \approx 2-2.5n_c, n_c being critical composition at Me…
Conductance fluctuations near Anderson transition
Arindam Ghosh, A. K. Raychaudhuri
In this paper we report measurements of conductance fluctuations in single crystal samples of Si doped with P and B close to the critical composition of the metal insulator transit…
Low energy excitations in crystalline perovskite oxides: Evidence from noise experiments
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report measurements of 1/f noise in a crystalline metallic oxide with perovskite structure down to 4.2K. The results show existence of localized excitations with a…
Kinetics of electric field induced oxygen ion migration in epitaxial metallic oxide films
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report the observation of curent induced change of resistance of thin metallic oxide films. The resistance changes at a very low current (current density $J \geq 1…
